Therefore, these two phases are linked by a transition zone which shows elastoplasticity

Insight into a model for large strain anisotropic elastoplasticity
The material behavior of the film is described by classical elastoplasticity accounting for large deformations.
In the present analysis, as mentioned above, it is assumed that the material behavior is adequately described by classical elastoplasticity.
It seems appropriate to emphasize that the present analysis is restricted to classical elastoplasticity with material properties pertinent to a polymeric film.
The investigation is restricted to polymeric films modeled by standard elastoplasticity but based on the stress field characteristics presented in previous investigations for a similar situation, it could be argued that this conclusion applies also for other types of material behavior.
Note that the iteration scheme for the quasilinear equations arising from elastoplasticity
has first been given in  and then developed in [3,6,7].
The first three chapters are devoted to the elastoplasticity
theory applied to soils and sedimentary rocks.
This finding was later confirmed for strain-hardening elastoplasticity, by Wredenberg and Larsson.
In this analysis, as indicated above, it was assumed that the material was adequately described by either classical elastoplasticity or the standard Drucker-Prager (32) material model describing pressure-sensitive flow.
Finally, in the context of theory and numerics, it should be emphasized once again that the scheme presented here is essentially the same as the one presented in a parallel article by Wredenberg and Larsson, (28) but in this investigation, only the influence from different mechanical and geometrical quantities at classical elastoplasticity was studied.
